Abstract
Coils in respective poles are all wound in the same shape. The coils are wound such that one of the winding ends in a predetermined layers, for a single turn, is passes to an adjacent layer, or single turns at the winding ends in a predetermined layer are wound to different adjacent positions, whereby the cross-sectional shape of the coils is unsymmetrical. The coils are wound such that part of each coil crosses or contacts an intermediate line bisecting the angle formed between the axes of the coils.
Claims14
A rotary electric machine having a stator having an annular array of poles with respective coils wound therearound, wherein,
- each of said coils is wound in an asymmetrical cross-sectional shape with respect to said poles in a plane perpendicular to the axis of said stator, and
- wherein one of adjacent ones of said coils has a portion extending beyond or held in contact with a tangential line interconnecting ends of adjacent layers of the other one of said adjacent ones of said coils, in the plane perpendicular to the axis of said stator.
